61822-2ZR Thin Wall Deep Groove Ball Bearing 110x140x16mm Double Metal Shield Thin Section Bearing

1. Product Overview

61822-2ZR single row thin-wall deep groove ball bearing, metric dimension 110×140×16mm, interchangeable with 61822-2RZ thin series bearing.
Code Definition

• 618: Ultra thin wall lightweight deep groove ball series
• 22: Size code for 110mm bore
• 2ZR: Double non-contact stamped iron dust shields for dry dust environment

Ultra thin cross-section saves axial installation space. Standard deep groove raceway bears radial load and light bidirectional axial load. Double Z iron shields block dry dust without extra friction loss, pre-filled standard lithium grease, widely used for compact automation equipment, light gearboxes and thin rotary assemblies.

2. Technical Specifications

Drawings and low-noise durability test reports available on request.

3. Core Advantages

1. Ultra thin wall lightweight design adapts narrow limited installation space
2. Double non-contact Z iron shields block dry dust, low friction high speed performance
3. Deep groove geometry supports radial and light bidirectional axial combined loads
4. Mirror polished steel balls deliver low noise stable continuous rotation
5. Compact lightweight structure reduces overall equipment weight
6. Universal standard dimensions for direct aftermarket replacement
7. Stamped steel cage prevents ball shifting under slight vibration
8. Customizable clearance, precision grade and outer ring laser marking

4. Application Scenarios

• Compact automated industrial equipment thin rotary shafts
• Light-duty small gearboxes and miniature speed reducers
• Medical thin rotary transmission and precision testing machinery
• Textile light roller and packaging compact transmission parts
• Small fan, thin motor and low-space automation rotary assemblies

Suitable for OEM production and aftermarket maintenance of thin compact light industrial machinery.
